To ad whome't may conce/m.

citizen of the United States, and residing at St. Louis, in lthe Stateof Missouri, have invented a certain new and useful Improvement iInEnveiopJaking Machines, of which the following is a specification.

This invention relates to envelop making machines, and more particularly, to an at tachment for such a machine, adapted to attach the transparency or panel to an address opening in the envelop-face.

One o f the'objects of this invention is to construct mechanism which may be ern bodied Iin a machine as built, or applied as an' attachment to an existing machine.

'Another -object is to Vprovide mechanism `Which will accurately' and positively posi- Ation and apply a panel in correct relation with v'respect to 'the envelop blank and 'the j" .opening therein, and which is capable of adj ustment.

rso

' v Another object 1s to provide: means for-retaining the panel during its posltionlng movement, and for discharging the v`lv "Another object is to provide mechanism whereby a continuous panel strip 1s fed to 25 the machine, from the end of 'which strip a panelis cut and applied to the blank.-

panel on the envelop blank.

. Further objects will appear from the detail description taken in connection with the accompanying drawings, in which:

Yf Referring now more particularly to Figs. l and 2, which show a Well known form of envelop machine to which this' invention is applied in the form of an attachment, 10 designates the case or frame, which is supported by- :suitable standards, -and has mounted therebelovv the 4main drive shaft and the cams operating the various parts of:

the machine.. A bracket ,11 has bearings for a vertically reciprocating shaft 12, which has mounted, at its lower end, the main ickers 13 and 14 for' cementing the aps l' and D, and an auxiliaryipicker 15 for-'cementing the margin around the o ening E. The. pickers 13 and 14 are -ad]ust ably mounted on the lower end ofthepicker s haftl2 for adjustrne-nt longitudinally of the'machine,'and the auxiliary picker/lois' mounted for similar .-'adjustmet,' whereby the pickers 4may be 'adjustedpor different' sized blanks. l The cement applied tothe pickers bythe usual cementing roll 16.

It will be noted that A,the panel is -nioyfed underneath the plunger, but not against "its lower face, but close to the blank, the clearance being very small. .This action ise'specially. permitted as the curved 94 of the arms curve the panel upwnrdlysp that it Willl clear the creasingtablei e'n thoughthe clearance be very small. 'Vith this construction it is, thefefore, possible to position the panel very accurately with respect to the blank, and this position can be adjusted by the eccentric 83. T he machine ay, therefore, be adjusted to place the panel in any suitable position on the en volop. The panel is positively held byi at'- mospheric pressure acting uniformly, onf-'it surface, and is discharged pnenmatically the pressure of the air. This rio/emily' accu? rately positions'the panel on the blanl. r,but

` also acts to firmly attach it, so that itcannot lsu shift during the creasing. and foldingoperation performed by the plunger. will be ffl understood that m. an envelop machipeavhich lattaches a panel to an envelop, the plunger does not do any attaching, for t. ereason that this plunger performs merely a creasing operation and often stops one-fourth of an inch fromv the folding table. The actual pressing of the panel on the envelop is performed by the flap folders. In this construction, however, the pneumatic means positively positions and positively applies the Apanel to the blank. The invention is simple in construction, as Well as positive `in its action generally. It can Ylie-applied to any machine in the form of an attachment,

, and can also be embodied in a machine as built. By providing the ratchet teeth, overthrow is prevented, so that the panel strip Will be fed accurately. 4

It is obvious that various changes may be made in details of construction Without departing from the spirit of this invention. 'It is, therefore, to be understood that this invention is not to belimited to the specific construction shown and described.

Having thus describedthe-invention, what is claimed is:
